Hybrid tea rose plant named Devpajaro

ABSTRACT

A new hybrid tea rose plant producing red orange flowers.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of rose plant of the hybrid tea rose class which was originated by crossing as seed parent the variety known as `Jacqueline`, (U.S. Plant Pat. No. 2,183) and as pollen parent the variety known as `Prominent`, (U.S. Plant Pat. No. 3,380). The varietal denomination of this new rose is `Devpajaro`.

Among the novel characteristics possessed by this new variety which distinguish it from its parents and all other varieties of which I am aware are its attractive large red orange flowers suitable for growing under glass for cut flower production.

Asexual reproduction by budding of the new variety as performed in Watsonville, Calif. shows that the foregoing and other distinguishing characteristics come true to form and are established and transmitted through succeeding propagations.

COMPARISON WITH PARENTS

The new variety produces large flowers on sturdy stems. Flowers produced by both parents are orange, whereas `Devpajaro` flowers have more red/orange coloration and are larger.

BRIEF DESCRIPTION OF ILLUSTRATIONS

The accompanying illustration shows typical specimens of the vegetative growth and flowers of the new variety in different stages of development and depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.

DESCRIPTION OF THE NEW VARIETY

Parentage: Seedling.

Seed parent.--`Jacqueline` (U.S. Plant Pat. No. 2,183).

Pollen parent.--`Prominent` (U.S. Plant Pat. No. 3,380).

Class: Hybrid tea.

The following is a detailed description of my new variety, of new specimens grown under glass in Watsonville, Calif. in the month of September. The color terminology used is in accordance with the Royal Horticultural Society Colour Chart (RHSCC) and refers to plate numbers in the aforementioned color chart. Phenotypic expression may vary depending on light, environmental and cultural conditions.
